Color copier is showing color click on art showing as straight K in acrobat

[adamh]

We run high end color copiers. I have a document that is 4 color on page 1, straight K on page 2. I export into acrobat from indesign and when looking at the separations in acrobat, it shows page 2 as straight black. When I go to print the job on our color copier, I'm paying for color clicks for the black page.

Any idea why this could be happening?

seem that you machine cannot find out what color it used.
Normally this kind of machine depend on what you set in print dialog. If you set it as color print, it count color click, you set b/w print, it count b/w click.
For some machine, it can auto find out, I had try printing only 1 page have 1 color black only(not 4 color black)
although I set "color" in print dialog, when it print, it still count as b/w click.

Yeah you might want to send all your straight K pages separately in order to get it to count as a straight K click. You also might want to make sure that the PDF you're sending isn't in the RGB color space, as the "straight K" could actually be RGB Black. Your RIP or PPD (depending on the settings) might not be converting it to CMYK black before it prints, thus causing it to count as a color click.

Are you including marks in your pdf? I know this seems obvious, but even if the work is all black, the marks in registration would cause the page to be seen as CMYK.

Also, you might try sending just the black separation. (This also is rather obvious, I guess)

Just a couple of thoughts!

Hi Adamh,

I agree with color_prepress. Our Ricoh only looks at what we send. For us it depends on how we specifiy the file in the PS settings of the Print Driver. If we leave it on color, we get charged for color, even if the document is 100% K only pages. If we select Black and White, it works correctly.

The strange thing is, if I send three jobs to print, all with a 4C side and a straight K side, only one is recording color clicks for the K side. Its inconsistent. I can't find the commonality that's causing it.

I bet you are using a Fiery. Which RIP/DFE and device are you using?

Try sending the black plate as device gray instead of "black" by itself and see what happens. If you go through the prepressforums.com archives there's a bunch of info I wrote that may be of assistance.
